MTN670802 Schneider Push-button interface 2-gang plus Introduction：
The push-button interface for KNX has two (art. no.MTN670802) or four (art. no. MTN670804) inputs and outputs. The inputs can be used to establish binary statuses (via floating contacts) and the outputs can be used to activate control lamps (low current LEDs).
For example, by connecting floating push-buttons or switches to the inputs, you can use the KNX to perform a range of functions including switching, dimming,operating blinds and retrieving scenes, etc.
To check statuses, you can connect control lamps (low current LEDs, e.g. in the switch) to the outputs and activate them via KNX.
The contact supply voltage (SELV) for the connected buttons/switches and the control lamps comes from the push-button interface.
The push-button interface has a bus coupler.
